STAY AWAY from this kid!
If he's got a crush on you, is bigger than you and used to having his way, you risk more than having a bit of "casual" contact from him. I can understand your concern for his situation, but don't jeoparize your own safety because you want to "save" him from a less than perfect home life. I'll just be blunt here. He's an under-aged teenage boy who is bigger than you and could rape you if he wanted to. He could then say YOU made a pass at him and seduced him. If he's 15 that is statutory rape in most states.
Perhaps it is innocent flirting on his part, perhaps not. Err on the side of your own safety here. Find somewhere else to shop and don't bring him any more pizzas either. If you have tea with his mother, meet her at a restaurant. Under no circumstances should you ever be alone with that kid. EVER.
